That is, FS -ext4 we write files of 0.5 gigabytes, if there is <10 gigabytes left on the disk, we erase the oldest file. How to calculate the real resource in time, based on the recording speed (for example, 10 Mb / s) or the total amount of recorded data. For example for:

You need to start with the fact that 840Evo is a fresh 19nm TLC memory, and some models are generally chasing 10nm, so the resource there is 3-4 times less than that of the same Crucial M500 =(.
Consider 2700 rewriting cycles for MLC - 3000 rarely survives due to power failures, overheating, and other side effects
... Well, if we have a 960GB screw, then
(960000 * 2700) / 10 = 259200000 seconds, which is actually equal to 8 years for the M500
Well, the 840Evo will have 2.5-3 years
